Turk Telekom was ready for a digital transformation. The information and communications technology company is a leading provider of mobile, Internet, phone, and television products and services in the Turkish market. It serves more than 17.1 million fixed-line, 14.6 million broadband, 2.9 million TV, and 25.6 million mobile subscribers.

The company sought to modernize its infrastructure to support its business-critical systems and the delivery of agile cloud services to its customers. Turk Telekom also wanted to build a more sustainable and simplified network architecture.

The new architecture would need to support Turk Telekom’s core billing and charging applications and databases, as well as its SAP applications and its virtualization and cloud service platforms. The data volumes for Turk Telekom's core systems are growing by 20 percent every year, and the company was concerned that the current storage system wouldn’t keep up, leading to bottlenecks and poor performance.

Data Storage Dynamo

The company reached out to long time partner Hitachi Vantara to explore data storage solutions that would support demanding new applications, boost performance, and reduce operating expenses. Turk chose to deploy Hitachi Vantara VSP 5600 arrays and Hitachi Vantara VSP 5200 arrays, enabling the company to switch from hybrid disk to non volatile memory express (NVMe) storage. That shift has improved performance and reduced data center space and related expenses.

The new system is powered by Hitachi Storage Virtualization Operating System (SVOS), with enhanced data reduction technologies that enable customers to store more user data within their purchased capacity.

Managed through the Hitachi Ops Center Administrator, Analyzer, and Protector, the new system has simplified storage management. Tasks such as provisioning, data protection, bottleneck analysis, and reporting can be set up within minutes. It provides a common point of control for all arrays and features API libraries that support integration with third-party tools. Using Hitachi Ops Center, Turk Telekom has reduced by 87 percent the time spent on storage management tasks.

Focus on Sustainability Pays Off

The new storage infrastructure has improved reliability and availability for its business and consumer customers. Turk Telekom has seen a five-fold increase in application response times and a four-fold increase in data throughput. The system takes up less space, dramatically decreasing Turk Telekom's total footprint from 23 cabinets to only nine. That in turn, has decreased power and cooling requirements by about 60 percent, reducing Turk Telekom's carbon footprint and dropping the total cost of ownership by about 30 percent.

Hitachi Vantara uses patented technologies within its storage systems to reduce power consumption, enabling its customers to meet or exceed their sustainability goals and save without sacrificing performance. For more than a decade, Hitachi Vantara has focused on reducing CO2 emissions in the VSP platform and has earned U.S. Energy Star certifications for several models.
